An Islamic State supporter who believes victims of terror attacks will burn in hell has been working as a teaching assistant, a Mail on Sunday investigation can reveal.

Imran Miah, 27, who has taught at a number of secondary schools in Britain, set out his vile agenda on Facebook and Instagram. He warned that religious opponents face attack with a ‘blunt butter knife’ (there's a joke in there somewhere) and issued a series of deeply disturbing homophobic statements. In one sickening post, he endorsed the barbaric execution of homosexuals.

As well as celebrating IS military victories on Facebook, Miah also uploaded a photograph of the terror group’s black flag and mocked the traditional minute’s silence for its victims.

A supply teaching assistant, Miah is believed to have worked at a number of state schools in London and beyond.

Last night, politicians reacted with disbelief that someone with such views could work in schools and called for an urgent police investigation. In common with all teachers, Miah would have been vetted by the criminal record checking service. But as he used a pseudonym online, his rants apparently went undetected.

In recent years the Government have grown increasingly concerned about the risk of radicalisation in schools, though their fears have normally been confined to faith schools and attempts to introduce a radical Islamist ethos.

Last year, tens of thousands of teachers were put through a mass counter terrorism training programme to help them spot and report potential extremists.

Worryingly, Miah, who lives in Manor Park, East London, is understood to have taught only in state schools.

Our enquiries also revealed that the boxing and martial arts enthusiast posted an advertisement for the nearby Ilford gym that was used by the three London Bridge attackers as an impromptu headquarters before they mowed down three people and killed five others in knife attacks last month.

All his abhorrent sentiments featured on his Facebook account, whose pages were open to public view while he was teaching. However, inquiries by this newspaper forced Miah – who uses the name Imran Ibn Fareed on social media – to remove them last week.

But not before he expressed regret at the fall of Mosul, Iraq’s second city, which had been in the hands of IS militants, who carried out public beheadings, forced Yazidi women into sexual slavery and even banned music. He said: ‘From the ashes of Mosul will rise a generation who love Allah and Allah loves them, they will not fear the blame of the blamers. They will be a thorn in the eyes, a spear in the chest and a raging fire in the hearts of the oppressors.’

Miah also expressed vile sectarian hatred of Shia Muslims, who are the second sect of Islam. He said: ‘Stinking Shia Rawafidh [rejectors] best stop Friend Requesting me on fb. Return to Islam you Murtaddeen [apostates] and only then you’re my brother in faith, till then, nothing stands before the Muwahhid [believer in one God] and the likes of your kind except a blunt butter knife.’ He placed an icon of a knife next to the post.

Lord Carlile, the former independent reviewer of terror legislation, said Miah’s online statements warranted a police investigation. He said they may breach the Terrorism Act of 2006 – which bans indirect encouragement of terrorism – as well as hate crime laws.

Compare and contrast the fate of Rachel Booth a dinner lady at Moor Nook Primary School in Preston who was suspended immedaite when she was seen at the march in support of the victims of the Manchester jihad bomb attack, organised by, amongst others, Tommy Robinson. It was called "March Against Islamic Hate" and was not an EDL event. However Tommy's name provokes a hysterical reaction whatever he does.

The march was held on June 11 in the wake of the Manchester bomb attack and Rachel says she went as a “heartbroken” mother and not an EDL supporter. “I’m nothing to do with the EDL, I just wanted to support the Lancashire families who lost children in the bombing. “I’m not racist – my husband and his family are mixed race. I’m being treated worse than a paedophile because I’ve been told I can’t go anywhere near the school.”

Rachel had been suspended with full pay pending an investigation. It describes taking part in the rally, which was captured on social media, as “potentially gross misconduct”.

Mr Robinson said: “I can’t believe it to be honest. It’s outrageous and unacceptable how the school have treated her. Rachel is just your average mum and it’s not right. The march was against hate and terrorism and included people from all different faiths and backgrounds. It was nothing to do with the EDL.”
